華嚴經探玄記 2.18

2.18

第二融攝者，有二：一直攝一切三世間盡，以具此三事方為佛故。三身二身但是三中智正覺攝，妙淨土及同生之身無不皆是此中所攝。二亦正報毛孔，依報塵中各重重具攝三世間等一切諸法，如帝網現，准思可見。

Second, concerning interpenetration and containment: there are two aspects. First, it directly and fully gathers all three worlds without remainder, because only when possessing these three matters does one become a Buddha. The three bodies and two bodies are only gathered within the enlightened beings among the three [worlds]; the wondrous pure lands and the bodies born together [with them] are all without exception gathered within this. Second, within each pore of the direct retribution and within each dust mote of the circumstantial retribution, all dharmas such as the three worlds are repeatedly and fully gathered, appearing like Indra's net, which can be seen by considering it accordingly.
